Fuel lines tank liners Barrier nylon resin

Regarding the special nylon resin in usage of forming fuel pipes and tank liners, the main materials are PA resin and related high barrier materials.

The role of nylon in automotive applications

Nylon (PA) is an engineering plastic widely used in the automotive industry due to its excellent mechanical properties, heat resistance, wear resistance, and oil resistance. Nylon is widely used in the manufacture of automobile parts, such as fuel pipes, fuel tanks, brake pads, etc.

Characteristics and Applications of Barrier Nylon Resin

Barrier nylon resin is mainly used to improve the barrier properties of nylon, especially the barrier properties of oxygen and nitrogen. This material can significantly extend the shelf life of food and medicine, and is also suitable for the needs of car fuel tanks and fuel pipes to improve their ability to block fuel vapor.

Application of fuel pipe and fuel tank

In the automotive field, the fuel tank and fuel pipe usually need to use high barrier materials to prevent fuel vapor leakage, which not only concerns the fuel efficiency of the car, but also involves environmental protection and safety issues. EVOH (ethylene-vinyl alcohol copolymer) is one of the commonly used barrier materials, which has good gas barrier properties and processing properties, and is usually blended with high-density polyethylene (HDPE) to manufacture multilayer fuel tanks.

Conclusion

The special nylon resin used in the fuel pipe and the inner lining of the fuel tank can effectively improve its barrier performance to fuel vapor by adding high barrier materials such as EVOH, thus ensuring the safety and environmental protection of automobiles. The selection and application of these materials are based on their excellent physical and chemical properties and long-term application verification in different industries.
